I mean, here's the thing, lets assume there's no 911 call ever made by this crazy dude and somebody conjured it up to give this an Islamic angle. Even that startling revelation wouldn't stop from letting the rest of the muslims getting maligned. Such are the crossroads we stand at as of right now. So, 911 call, no 911 call, doesn't make a difference in Islam not getting maligned.
As for ISIS, I mentioned in the other thread that they jumped the gun declaring this guy as their holy warrior. And the holy warrior turned out to be a fruit ball they so despise. But don't be surprised if ISIS doesn't have homosexual men in their rank and file already. Why else would you go to great lengths to curb homosexuality if not out of fear of wide spread gays in your own ranks?
